BUILDING BLOCK.

Application filed December 26, 1922. Serial No. 608,850.

To all whom t may concern:

Be it known that I, CLEMsoN A. MELTON, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Building Blocks; and l do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accon'ipanying drawings, and to the iigures ot reference marked thereon, which form a part ot this specilication.

rThis invention relates to building or tile and the primary object of the invention is to provide a building block which can be laid in courses in interlocking rows so that the wall structure will be light, durable and strong and so that ventilating spaces will be provided in the wall, both laterally and vertically; the building blocks being constructed so that they can be easily blocks matched in building the structure. The novel construction oi the building block will be clearly understood by reference to the following description in connection with the accompanying drawings, in which- Fig. l is a perspective view of' a corner of a partially completed wall constructed of blocks made in accordance with my invention.

Fig. 2 is a vertical, cross sectional View through a portion oi the wall, and

F 3 is a detail, perspective view oil one ot the blocks.

The block is preferably constructed substantially U-shaped in cross section; that is, it is provided with a horizontal wall l and two side walls 2 and 3. The side wall 3 is wider than the side wall Q; therefore, the block has a relatively long leg and a relatively short leg, both legs being co-extensive in length. The long leg is equal to the length ot the short leg plus the thickness of the horizontal wall l and the horizontal wall is provided with one o-r more slots, there being two shown in the present instance designated l and 5.

The block is preferably constructed of concrete or similar material having longi tudinal reinforcing bars or wires 6 and transverse reinforcing bars or wires 7. The blocks are laid in courses in double rows; that is, one short leg or wall 2 will interlock with a complementary short leg or wall 2 of a block laid parallel to it. One short leg of each complementary tile overlaps the complementary leg of another complementary tile so that the short legs extend into the grooves S of the respective tiles or blocks, as will be clearly seen by reference to Fig. 2.

The two tiles are secured together by courses ot' cement 9 and lO, the cement being laid upon the iioor of the groove 8 for one short leg 2 and upon the upper edge oit' the other short leg of the complementary member so that the floor of the groove of the second tile may rest upon it. In this manner the slots 4 and 5 of one set of blocks register with corresponding slots in the courses both below and above them and the grooves S of all ot the tiles in one layer of one course are longitudinally aligned so that there are spaces both horizontally and Vertically in the wall which prevent the acct:-

mulation of the moisture in the wall of the building.

The corner tiles or blocks are preferably constructed like the tile shown in Fig. l designated 1l; that is, the tiles or building blocks conform to the construction shown in Fig. 3 except that they are L-shaped.

From the foregoing it will be apparent that the tiles may be laid in courses in parallel rows; that is, two tiles will oonstitute each course, and that they will preterably be interlocked so as to provide a rigid wall structure.

that l claim and desire to secure by Letters-Patent is:

1. A wall comprising tile arranged in courses in parallel rows, the parallel rows in each course consisting of blocks substan tially U-shaped in cross section, each having a long leg and a short leg, the short leg of adjacent complementary tile in each row overlapping one another to prevent lateral movement between the tile.

2. A wall comprising tile arranged in courses in parallel rows, the parallel rows in each course consisting of blocks substan tially U-shaped in cross section, each having a long leg and a short leg, the short leg of adjacent complementary tile in each row overlapping one another to prevent lateral movement between the tile and cementitious material between the overlapping portions of the short legs to secure the tile together.

In testimony whereof I aiiix my signature.

CLEMSON A. MELTON.
